As others have mentioned, I can only feel that some people have the wrong attitude here if the FPP is seen as the only way to the RHS.
To be fair, if you're unwilling to use a house a security this is one of only 2 (along with Virgin) integrated schemes available. I wouldn't say this is a poor attitude, more a sensible one. Ofc there is the modular route as well, the pro's and cons of which have been discussed ad infinitum on here before.
